发明名称 Image sensing device, image processing apparatus and method, and memory medium
摘要 An image sensing device of this invention corrects sensitivity nonuniformity of an image sensing element. This image sensing device has an image sensing element (5) having a two-dimensional matrix of pixels, a first multiplier circuit (18) for multiplying the output from the image sensing element (5) output via an A/D converter (7) by horizontal linear correction data, a second multiplier circuit (19) for multiplying the product of the first multiplier circuit by vertical linear correction data, a selector (16) for selecting horizontal linear correction data, and a selector (17) for selecting vertical linear correction data. The device switches the selectors (16, 17) in accordance with the position (horizontal and vertical addresses) of the pixel of interest.
